An expert has suggested that an earlier diagnosis of Autism can offer a person a better prognosis for the future.
Keith Lovett, director of Autism Independent UK, said: "The rule of thumb is the earlier the diagnosis the better the prognosis."
His comment comes as the University of Kansas has revealed a piece of apparatus to help screen for Autistic spectrum disorders.
The automated voice analysis technology can pick up Autistic children's "distinctly different" pre-verbal vocalisations with a high rate of accuracy.
However, Mr Lovett suggested that most parents will "get a gut feeling that something isn't quite right" if their child is Autistic.
He said that parents who suspect that something could be wrong should "see a specialist in the field of Autism for a diagnosis to rule it in or rule it out".
There are around 2.3 million people in the UK who are affected by Autism, according to the National Autistic Society.
